HP Battery Replacement: The Removable-Pack Path vs. the Internal-Pack Path
XiongYing Zeng
Identify your path first. Removable packs sit under a latch on the bottom cover, visible without opening anything. Internal packs hide behind the bottom cover. Pre-2016 Pavilions and older ProBooks lean removable. Modern Pavilion, Envy, OMEN, and EliteBook models run internal.
Hidden screws are the internal path's trap. HP hides 2–4 screws under the rubber feet on many Pavilion and EliteBook models. Miss one and the cover cracks when you pry. Peel the feet first, every time.
Both paths share one rule. Disconnect or remove the battery before you touch any other component. The pack holds charge even with the laptop shut down.
1. Identify Your Path First
| Series | Path | Time | Tools |
|---|---|---|---|
| Pavilion 15-ab/17-g (2015–2017), ProBook 400 G1-G4, older EliteBook | A: Removable | 1–2 minutes | None |
| Pavilion 14/15/17 (2018+), Envy, Spectre, OMEN, Victus, EliteBook G5+ | B: Internal | 20–40 minutes | PH0 screwdriver, spudger, screw tray |
Flip the laptop over. If you see a release latch and a seam that separates a battery-shaped block from the chassis, you have a removable pack. If the bottom is one smooth panel held by screws, you have an internal pack. The latch decides your path.
2. Path A: The Removable-Pack Swap (60 Seconds)
- Shut the laptop down and unplug the charger. No tools needed for this path.
- Flip the laptop over. Find the two battery latches. One releases, one locks.
- Slide the release latch outward and hold it. The battery edge pops up on one side.
- Lift the battery out by its edge. It slides free at an angle. Set it aside.
- Slide the new pack in at the same angle until it clicks. Push the lock latch back to secure it.
The whole swap takes about 60 seconds, and you cannot damage anything if you skip the tools. This is the path where DIY beats every other option.
3. Path B: The Internal-Pack Swap (20–40 Minutes)
- Discharge and drain. Run the battery below 25%, shut down, unplug, then hold the power button for 15 seconds.
- Peel the rubber feet strips. Lift them with a fingernail or spudger tip. Note which screw heads they hide.
- Remove every bottom screw. Count them into a tray in the position they came from. HP mixes 2–3 lengths.
- Pry the cover off with the plastic spudger. Start at a corner, work around the edge, and listen for the clips clicking free. If a section resists, a screw remains.
- Disconnect the battery first. Locate the battery connector on the motherboard. Grip the plastic connector body and pull it straight out. Never pull the wires.
- Unscrew the battery bracket. Most packs use 4 screws. Slim Envy models add a second bracket near the hinge.
- Lift the old pack out. On Spectre models, slide the spudger under the pack and work the adhesive loose slowly. Everywhere else, it lifts free.
- Set the new pack in place. Line up the screw holes. Tighten the screws to snug, not tight.
- Reconnect the battery and close up. Push the connector in until it clicks. Snap the cover on, then return the screws to their original holes.
In my experience, step 5 decides whether the job succeeds. A connector pulled by its wires tears pins out of the board, and that repair costs more than the battery. Grip plastic, pull straight, and the rest of the job goes smoothly.
4. The Screw Map: Where HP Hides Fasteners
| HP Series | Bottom Screws | Hidden Screws | Head Type |
|---|---|---|---|
| Pavilion 14/15/17 (2018+) | 6–8 | 2 under rear feet | Phillips PH0 |
| Pavilion 15-bs (2017–2019) | 8–10 | 2 under rear feet | Phillips PH0 |
| EliteBook 840 G5-G6 | 5 | 0, all visible | Phillips PH0 |
| OMEN 15/16 | 8–10 | 0, all visible | Phillips PH0 |
| Spectre x360 | 4–6 | 2 under front strip | Torx T5 + Phillips |
EliteBook and OMEN put every screw in plain sight. Pavilion hides two under the rear feet. Spectre mixes Torx and Phillips heads and hides two under the front strip. The truth is, every cracked bottom cover I've seen started with someone prying against a screw they hadn't found. When the cover resists your spudger, stop prying and hunt for the screw you missed.

6. First Boot Problems and Their Fixes
| Symptom | Cause | Fix |
|---|---|---|
| Laptop won't power on | Connector not fully seated, or pack shipped in storage mode | Reseat the connector. Plug in the charger and wait 30 minutes. |
| "Plugged in, not charging" | Half-seated connector, or BIOS needs a reset | Reseat. Update the BIOS and chipset driver. If it persists, reseat again. |
| Battery reads 0% on first boot | Normal, packs ship at roughly 30% storage charge | Charge to 100%, leave plugged in 30 extra minutes. |
| Percentage jumps around | Normal for the first 1–2 cycles | Run one full discharge to 10%, then recharge to 100%. |
From what I've seen, nine of ten first-boot problems trace back to the connector. Reseat it firmly and the symptoms disappear. If the laptop still refuses the battery after a BIOS update and two reseats, contact the battery seller for a warranty replacement.

How to Buy an HP Laptop Battery: The 6 Checks That Matter →Frequently Asked Questions
How do I know if my HP laptop has a removable battery?
Flip the laptop over and look for a release latch and a seam that separates a battery-shaped block from the chassis. If you see them, the pack slides out — no tools needed. If the bottom is one smooth screw-secured panel, the battery is internal. Pre-2016 Pavilions and ProBook 400 G1-G4 models lean removable; everything modern runs internal.
How do I remove a removable HP laptop battery?
Shut down, unplug, and flip the laptop. Slide the release latch outward and hold it. The battery edge pops up, and you lift the pack free at an angle. Slide the replacement in at the same angle until it clicks, then push the lock latch back. The whole swap takes about 60 seconds.
How do I open an HP laptop to replace the internal battery?
Peel the rubber feet first — HP hides 2 screws under the rear strip on most Pavilion models. Remove every bottom screw into a tray, then pry the cover with a plastic spudger, working corner to corner. Disconnect the battery connector from the motherboard before unscrewing the pack. Grip the plastic connector body, never the wires.
Do I need to disconnect the battery before removing other parts?
Yes, always. The pack holds charge even with the laptop shut down, and it feeds the board the moment you touch metal components. Disconnect the battery as your first action after opening the cover, before you remove anything else. This rule prevents shorts during RAM or SSD work too.
Why won't my HP laptop turn on after a battery replacement?
Two usual causes. The battery connector sits half-seated, so the board sees no battery — reseat it firmly. Or the pack shipped in storage mode at roughly 30% charge, so the laptop needs the charger connected and 30 minutes before it boots on its own. If neither works after a BIOS update, contact the seller for a warranty replacement.
What do I do with the old HP laptop battery?
Never throw a lithium pack in the trash. Recycle it at an R2 or e-Stewards certified e-waste recycler — Best Buy and many office stores run free drop-off programs. If the old pack is swollen, place it in a fireproof container and take it to the recycler the same day. Some retailers include a prepaid recycling kit with the new battery.
